The message authentication code functions output the \s-1MAC\s0 of a supplied input
file.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print a usage message.
.IP "\fB\-in\fR \fIfilename\fR" 4
.IX Item "-in filename"
Input filename to calculate a \s-1MAC\s0 for, or standard input by default.
Standard input is used if the filename is '\-'.
Files are expected to be in binary format, standard input uses hexadecimal text
format.
.IP "\fB\-out\fR \fIfilename\fR" 4
.IX Item "-out filename"
Filename to output to, or standard output by default.
.IP "\fB\-binary\fR" 4
.IX Item "-binary"
Output the \s-1MAC\s0 in binary form. Uses hexadecimal text format if not specified.
.IP "\fB\-macopt\fR \fInm\fR:\fIv\fR" 4
.IX Item "-macopt nm:v"
Passes options to the \s-1MAC\s0 algorithm.
A comprehensive list of controls can be found in the \s-1EVP_MAC\s0 implementation
documentation.
Common parameter names used by \fIEVP_MAC_CTX_get_params()\fR are:
.RS 4
.IP "\fBkey:\fR\fIstring\fR" 4
.IX Item "key:string"
Specifies the \s-1MAC\s0 key as an alphanumeric string (use if the key contains
printable characters only).
The string length must conform to any restrictions of the \s-1MAC\s0 algorithm.
A key must be specified for every \s-1MAC\s0 algorithm.
.IP "\fBhexkey:\fR\fIstring\fR" 4
.IX Item "hexkey:string"
Specifies the \s-1MAC\s0 key in hexadecimal form (two hex digits per byte).
The key length must conform to any restrictions of the \s-1MAC\s0 algorithm.
A key must be specified for every \s-1MAC\s0 algorithm.
.IP "\fBdigest:\fR\fIstring\fR" 4
.IX Item "digest:string"
Used by \s-1HMAC\s0 as an alphanumeric string (use if the key contains printable
characters only).
The string length must conform to any restrictions of the \s-1MAC\s0 algorithm.
To see the list of supported digests, use \f(CW\*(C`openssl list \-digest\-commands\*(C'\fR.
.IP "\fBcipher:\fR\fIstring\fR" 4
.IX Item "cipher:string"
Used by \s-1CMAC\s0 and \s-1GMAC\s0 to specify the cipher algorithm.
For \s-1CMAC\s0 it must be one of \s-1AES\-128\-CBC\s0, \s-1AES\-192\-CBC\s0, \s-1AES\-256\-CBC\s0 or
\&\s-1DES\-EDE3\-CBC\s0.
For \s-1GMAC\s0 it should be a \s-1GCM\s0 mode cipher e.g. \s-1AES\-128\-GCM\s0.
.IP "\fBiv:\fR\fIstring\fR" 4
.IX Item "iv:string"
Used by \s-1GMAC\s0 to specify an \s-1IV\s0 as an alphanumeric string (use if the \s-1IV\s0 contains
printable characters only).
.IP "\fBhexiv:\fR\fIstring\fR" 4
.IX Item "hexiv:string"
Used by \s-1GMAC\s0 to specify an \s-1IV\s0 in hexadecimal form (two hex digits per byte).
.IP "\fBsize:\fR\fIint\fR" 4
.IX Item "size:int"
Used by \s-1KMAC128\s0 or \s-1KMAC256\s0 to specify an output length.
The default sizes are 32 or 64 bytes respectively.
.IP "\fBcustom:\fR\fIstring\fR" 4
.IX Item "custom:string"
Used by \s-1KMAC128\s0 or \s-1KMAC256\s0 to specify a customization string.
The default is the empty string "".
